教学电磁波谱介绍红外线的性能与应用时,由于未有现成的实验仪器,教师不做实验,加上红外线是看不见摸不着的,学生很难学得上手,听课时毫无兴趣.为了提高教学质量,我制作了红外线实验器,经教学实践,效果很好.1实验仪器的制作(1)把内壁后面镀有银,功率为250W带有灯座和电源插头的 Teaching electromagnetic spectrum introduces the performance and application of infrared, because there is no ready-made experimental equipment, teachers do not do experiments, plus infrared is invisible and inaccessible, students are difficult to learn to use, no interest in class. In order to improve teaching Quality, I made an infrared experimental device, the practice is very good by teaching practice. 1 production of experimental instruments (1) silver plated on the inner wall, power is 250W with a lamp holder and power plug
